IMPROVEMENT IN OlL-PRESSES.

Specification forming part of Letters Patent No. 205,637, dated July 2,1878; application filed J une 5, 1878.

To all whom it may concern:

Be it known that I, JOHN TnonAs HAR- BINE, of Xenia, in the county ofGreen and State of Ohio, have invented certain new and usefulImprovements in Oil-Presses5 and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain improvements in oil-presses, or thatclass of presses used for the purpose of compressing various substances,principally meal of certain seeds, in order to obtain the oil containedtherein; and it consists in the adaptation of the press for my improvedmats or partitions, forming the subject-matter of a separate applicationfor patent.

My invention further consists in certain improvements in the box orcylinder-bottom of the press, as will be hereinafter more fully shownand described.

In the drawings, Figure 1 is a perspective view of the press charged andready for operation, and Fig. 2 is a vertical sectional view of thepress.

Similar letters of reference denote corresponding parts in all thefigures.

A is the press. This consists of four columns or uprights, a a, unitingthe top piece B with the base or cylinder-bottom C). The latter consistsof a solid box or casting, in which is sunk a recess, 1), to receive theoil,

which is conducted through a perforation or spout to vessels outside thepress.

The casting O has a central perforation for the ram E, worked byhydraulic or other pressure, and around the perforation is formed a rimor collar, c.

By this construction the pressman' is enabled, at any time, to detect ifthe packing around the ram is leaking, as, if such is the case, thefluid used for forcing it will run over the upper edge of the collar 0and down the sides thereof, whereas if the collar was left off, as usualin this kind of presses, the bottom of the box being covered with oil,such discovery could not be made, and a large proportion of the powerwould be lost.

It will be obvious that old presses of the construction now usuallyemployed may be readily supplied with my improvement by placing upon thecylinder-bottom, which is flat, a box made of cast or wrought iron andembodying my improvement. A simple collar and rim, suitably arranged andsecured, would practically serve the same purpose.

The sides I? P and rear end of the pressbox are formed by plates ofsheet metal, either plain or corrugated. In the latter case thecorrugations form channels for conducting the oil to the box orreceptable b. I

In order to simplify the reconstruction of old presses, and also to makethe box more readily removable, I prefer to construct each of the sidesof a separate plate, and to bolt the side plates to the rear 'one, asshown. The front side of the press-boxis open ;'but, while the operationof pressing is going on, I prefer to cover it with a detachable plate,P, which formsa lid or cover, and serves to prevent oil from splashingout at the front side of the press. The lower end of plate P is notchedto enable it to enter the box, and it is retained in position by a catchor equivalent device at the top of the press.

The operation of my invention will be readily understood. I place uponthe rain-plate D one of my improved mats, forming the subject-matter forseparate application for patent; then upon this a charge of the materialto be pressed then another mat, another charge, and so on until thepress-box is full. The front plate or cover is now adjusted, andpressure may then be applied in the usual manner.

It will be observed that when the press-box is packed full the pressureupon the charges commences at once, while in other presses the ramfrequently has to travel a distance of from one to three feet beforethis is the case, resulting in great loss of power. The grooves orcorrugations in the sides conduct the oil, as it escapes, to the box orreceptacle below, and, when sufficiently drained, the cakes may bereadily removed after detaching the front plate or cover of thepress-box.

Having thus described my invention, Iclaiin and desire to secure byLetters Patent of the United States- As an improvement in oil-presses,the top In testimony that I claim the foregoing as piece B, uprights aa, cylinder-bottom O, havmy own Ihave hereto aflixed my signature in ingrecess or box I) and collar 0, and the presspresence of two Witnesses.
